SAN FRANCISCO - Regardless of their personal numbers or the quality of the team, at least one Marlins starter seems to deliver a special performance at AT&T Park every season. Saturday, it was Tom Koehler. Behind Koehler's seven shutout innings, the Marlins topped the Giants 5-0 for their second win in three games so far in the series. As poorly as this 11-game road trip began (2-7), the Marlins with a win Sunday can return to Miami 5-6. If nothing else, they'll open their next homestand Tuesday no worse than a game over .500.
